Is it bad to create pre-signed URLs every time for frequently S3 object access?

Question

Previously I have asked a question about s3 presigned URL. One expert replied that s3 presigned urls are only for download purpose. He said ```Typically we recommend to generate the presigned URLs only when you want to download the object.```. I just want to access s3 objects frequently with presigned URLs.

Accepted Answer

Hi Amplify_lover,

Presigned URLs are **typically** used for download purposes, but they can also be used for [upload](https://docs.aws.amazon.com/AmazonS3/latest/userguide/PresignedUrlUploadObject.html).

That said, there isn't any cost associated with presigned urls so there isn't a problem with generating many of them, so if it suits your use-case, use it to your heart's content!
